Answer:
c. 4^3 * 5^2 (1600)
d. 9^4 * 7^2 (321489)
Step-by-step 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
