Question

3^10 + 3^10 + 3^10=
a)9^30
b)3^30
c)9^10
d3^11

Answer 1

As a^m+a^m+a^m=a^m+m+m or (a+a+a)^m {WHEN BASES ARE SAME WE CAN ADD THE BASES TOGETHER AND PUT THE POWER (IN CASE OF ADDITION) AND WHEN POWERS ARE SAME WE CAN ADD THE POWERS AND LET THE BASE REMAIN SAME}

So,

(3+3+3)^10 and 3^10+10+10 is also true (only because both the basesa nd the powers here are the same)

So,

9^10 and 3^30

So option b and c are correct
