Question

Решите карточку пожалуйста. Очень надо.

Answer 1

$1.1) 5^2*5^9=5^1^1;$
$1.2) 2^8:2^4=2^4;$
$1.3)(3^3)^2=3^6;$
$1.4) [tex]1.4)4^8*7^8=(4*7)^8=28^8$(3^3)^2=3^6;[/tex]
$1.5)(x^2)^5:x^3 = x^1^0:x^3=x^7.$
$2.1)(5m^2y^3+3m^3y^2-m)-(3m^2y^3+2m+3m^3y^2) =$ $5m^2y^3+3m^3y^2-m-3m^2y^3-2m-3m^3y^2 =$ $2m^2y^3-3m;$
$2.2)3x^2(b+2x)-2x(2b^2x+3x^2) = 3x^2b+6x^3-4b^2x^2-6x^3=$ $3x^2b-4b^2x^2;$
