Question

I need help on question c and d

Answer 1

c. 4^3 * 5^2 (1600)

d. 9^4 * 7^2 (321489)

Explanation:

Hi!

Remember that exponents are the number times itself (2*2 = 2^2).

So, in c, we have 4 times 4 times 4. We have 4 multiplied by 4 3 times. We can also write this as 4^3.

We also have 5 times 5. We can also write this as 5^2.

However, we need to multiply 5^2 by 4^3. So:

4^3 times 5^2 or 1600.

d.

Let's group the similar numbers together.

9 x 9 x 9 x 9 and 7 x 7

There are 4 9's, so 9^4.

There are 2 7's, so 7^2

Multiply the 2.

9^4 * 7^2
