Answer 1

Resposta:

A) 5a×5a= 2

$5a \times 5a = 25a {}^{2}$

$7 x \times 9y = 63x{}^{2}$

$8x {}^{3}y {}^{2} \times 9x {}^{3}y = 72x {}^{6} y {}^{3}$

$16a {}^{2}b {}^{3} \div 8a \: b { }^{2} = 2a {}^{3} b {}^{5}$

$45m {}^{3} w {}^{3} \div 9m {}^{2} w {}^{3 = } 5m {}^{5} w {}^{6}$

$(3x {}^{2}) {}^{2} = 9x {}^{4}$

$( - 6a {}^{2} ) {}^{3} = - 216a {}^{6}$

EU ACHO QUE É ISSO
