Question

please answer this question I am mark will be brainliest and like ​

Answer 1

Step-by-step explanation:

[2.5*1^5*(0.5)^2] * [1.2*1^2*(0.5)^2]

=[2.5*1*0.25] *[1.2*1*0.25]

=0.625* 0.3

=0.1875

Please mark me as the brainliest

Answer 2

Answer:

Hope this brings smile on your face :)

$(2.3a {}^{5} b {}^{2} ) \times (1.2a {}^{2} b {}^{2} ) = 2.3 \times 1.1(a {}^{5} .a {}^{2})( b {}^{2} .b {}^{2} ) \\ = 2.53(a {}^{5 + 2})( b {}^{2 + 2} ) \\ = 2.53(a {}^{7})( b {}^{4} ) \\ (sub \: \: a = 1 \: and \: \: b = 0.5 \: in \: the \: above \: equation)\\ (2.3a {}^{5} b {}^{2} ) \times (1.2a {}^{2} b {}^{2}) = 2.53(1) {}^{7} (0.5) {}^{4} \\ = 2.53 \times 1 \times 0.5 \times 0.5 \times 0.5 \times 0.5 \\ = 2.53 \times 0.25 \times 0.25 \\ = 2.53 \times 0.0625 \\ = 0.158125$
