PROBLEM

Which expression is greater: 4×1094 \times 10^{9} or 2,000,0002,000,000? Choose from 8×10158 \times 10^{15}, 8×10548 \times 10^{54}, 8×10168 \times 10^{16}, 8×10638 \times 10^{63}.

STEP 1

Assumptions1. The expression "4×1094 \times10^{9} is as great as ,000,000,000,000" means that 4×1094 \times10^{9} is equal to ,000,000,000,000 times some number.
. We are looking for that number.

STEP 2

First, we need to set up an equation to represent the statement "4×1094 \times10^{9} is as great as 2,000,0002,000,000 times some number". We can represent the unknown number as xx.
4×109=2,000,000×x4 \times10^{9} =2,000,000 \times x

STEP 3

Now, we need to solve this equation for xx. We can do this by dividing both sides of the equation by 2,000,0002,000,000.
x=×1092,000,000x = \frac{ \times10^{9}}{2,000,000}

STEP 4

Now, we can simplify the right-hand side of the equation.
x=4×1092×106x = \frac{4 \times10^{9}}{2 \times10^{6}}

STEP 5

We can simplify further by dividing the coefficients (4 and2) and subtracting the exponents of10 (9 and).
x=2×103x =2 \times10^{3}

STEP 6

So, the number we are looking for is 2×1032 \times10^{3}, which is equal to 2,0002,000.Now, let's check each of the given options and see which one equals 2,0002,000 when divided by 2,000,0002,000,000.

STEP 7

Check the first option.
×10152,000,000=4×109\frac{ \times10^{15}}{2,000,000} =4 \times10^{9}This is not equal to 2,0002,000, so the first option is not correct.

STEP 8

Check the second option.
8×10542,000,000=4×1048\frac{8 \times10^{54}}{2,000,000} =4 \times10^{48}This is not equal to 2,0002,000, so the second option is not correct.

STEP 9

Check the third option.
8×162,000,000=4×\frac{8 \times^{16}}{2,000,000} =4 \times^{}This is not equal to 2,0002,000, so the third option is not correct.

SOLUTION

Check the fourth option.
8×10632,000,000=4×1057\frac{8 \times10^{63}}{2,000,000} =4 \times10^{57}This is not equal to 2,0002,000, so the fourth option is not correct.
None of the given options make the statement "4×1094 \times10^{9} is as great as 2,000,0002,000,000" true. There seems to be a mistake in the problem.
