Answer 2

Step-by-step explanation:

1)2²×3⁴×4/2×32

=8×81×4/64

it can be also written as= 8×9²×2²/8²

=8×(9×2)²/8²

=8×18²/8²

=18²/8 or 9²/2 or 18²/2³

2)[(5²)³×5⁴]÷5^7

=[(5^2×3)×5⁴÷5^7

=(5^6)×5^4÷5^7

=5^6+4÷5^7

=5^10÷5^7

=5^10-7

=5^3

3)25⁴÷5³

=it can also written as =(5²)⁴÷5³

=5^2×4÷5³

=5^8÷5³

=5^8-3

=5^5

4)3×7²×11^8/21×11³

=7×11^8/11³

=7×11^5

5)3^7/3⁴×3³

=3^7/3^4+3

=3^7/3^7

=1

6)2°+3°+4°

=1+1+1

=3

7)2°×3°×4°

=1×1×1

=1

8)(3°+2°)×5°

=(1+1)×1

=2×1

=2

9)2^8×a^5/4³×a³

=after canceling we get 2²×a²

=(2a)²

10)[a^5/a³]×a^8

=after canceling result is a²×a^8

=a^2+8

=a^10

11)4^5×a^8×b^3/4^5×a^5×b²

=after canceling result is a³b

12)(2³×2)²

=(2^3+1)²

=(2⁴)²

=2^4×2

=2^8
