Answer 1

Răspuns:

$\bf \big(7^{14}\cdot5\big)^{2 }: 7^{26} = 7^{14\cdot2} \cdot5^2 : 7^{26} =$

$\bf 7^{28} \cdot5^2 : 7^{26} = 7^{28-26} \cdot 5^2= 7^{2} \cdot 5^2=$

$\bf \big(7\cdot5\big)^{2 }=\red{\underline{~35^{2}~}}$

Answer 2

$\it(7^{14}\cdot5)^2:7^{26}=\dfrac{7^{28}\cdot5^2}{7^{26}}=7^2\cdot5^2=35^2=1225$
