Answer:

a=2^2

b=3^5

c=4^3x5^2

d=7^2x9^4

Step-by-step explanation:

All you have to do is write the number that is already there and power it by number of times it is repeated.

If there are two different numbers in a question (like c and d) you should start with the smaller number and then follow with the larger on with a x/times symbol between them.

[tex]\underbrace{a\times a\times a\times...\times a}_{n}=a^n[/tex]

[tex]A)\ \underbrace{2\times2\times2}_{3}=2^3\\\\B)\ \underbrace{3\times3\times3\times3\times3}_{5}=3^5\\\\C)\ \underbrace{4\times4\times4}_{3}\times\underbrace{5\times5}_{2}=4^3\times5^2\\\\D)\ 9\times7\times9\times9\times7\times9=\underbrace{9\times9\times9\times9}_{4}\times\underbrace{7\times7}_{2}=9^4\times7^2[/tex]
