Question

simplify the following: (-3)^4×7^4​

Answer 1

Answer:

Step-by-step explanation:

1) When the exponent is same we multiply the bases and the exponent remains same

Therefore ( -3)^4 X 7^4 ={ (-3)*7}^4 =(-21)^4

Answer 2

Answer:

when the powers are same

GENERAL EQUATION :

a^m×b^m= (a×b)^m

so,

(-3)^4×7^4= (-3×7)^4

=(-21)^4

simplification:

(-21)^4

calculation:

= -21×-21×-21×-21

= 441×441

= 194,481
