Answer 1

$\displaystyle 0,7a^3b^2*\frac{1}{7}a^2b^4=\frac{7}{10}a^3b^2*\frac{1}{7}a^2b^4=\frac{1}{10}a^3b^2a^2b^4=0,1a^5b^6$

Answer 2

Объяснение:

$0.7a {}^{3} b {}^{2} \times \frac{1}{7} a {}^{2} b {}^{4} =0.7^{1}a^{3}b^{2}\times \left(\frac{1}{7}\right)^{1}a^{2}b^{4} =0.7^{1}\times \left(\frac{1}{7}\right)^{1}a^{3}a^{2}b^{2}b^{4} =0.7^{1}\times \left(\frac{1}{7}\right)^{1}a^{3+2}b^{2+4} =0.7^{1}\times \left(\frac{1}{7}\right)^{1}a^{5}b^{2+4} =0.7^{1}\times \left(\frac{1}{7}\right)^{1}a^{5}b^{6} =\frac{1}{10}a^{5}b^{6} =0.1a ^ { 5 } b ^ { 6 }$
