calculați: tot exercițiul, vă rog​

Answer 1

Răspuns:

a)(2²×2⁵):2⁶=(4×32):64

=128:64

=2

b)(3²)³:3⁵=3²×³:3⁵

=3⁶:3⁵

=3⁶-⁵

=3¹=>3

c)(3×3²×3³):3⁶

=(3×9×27):729

=(27×27):729

=729:729

=1

d)(5⁶:5⁴)⁸:(5³)⁵=

=(5⁶-⁴)⁸:(5³×⁵)

=(5²)⁸:5¹⁵

=5²×⁸:5¹⁵

=5¹⁶:5¹⁵

=5¹⁶-¹⁵

=5¹

=5

e)(a⁵×a²)³:(a⁴)⁵=

=(a⁵+²)³:a⁴×⁵

=(a⁷)³:a²⁰

=a⁷׳:a²⁰

=a²¹:a²⁰

=a²¹-²⁰

=a¹

f)x×(x⁵:x⁴)²=

=x×(x⁵-⁴)²

=x×(x¹)²

=x×x¹×²

=x×x²
