Question

Помогите срочно надо!!!

Answer 1

1.а)=х^16
б) =(-ах)^11
2. а) =х²
б) =(а-b)²
3.а) у^17
б) у^3 * у^5
в) у^10
г) у^6 * у^4
4.
$\frac{ {0.2}^{3} \times { ({0.2}^{2} )}^{3} }{ {0.2}^{8} } = \\ = \frac{ {0.2}^{3} \times {{0.2}^{6}} }{ {0.2}^{8} } = \\ = \frac{ {0.2}^{9} }{ {0.2}^{8} } = 0.2$
5.
$\frac{ {x}^{3} \times { ({x}^{5} )}^{7} \div {x}^{11} }{ {x}^{23} } = \\ = \frac{ {x}^{3} \times { {x}^{35} } \div {x}^{11} }{ {x}^{23} } = \\ = \frac{ { {x}^{38} } \div {x}^{11} }{ {x}^{23} } = \\ = \frac{ {x}^{27} }{ {x}^{23} } = {x}^{4}$
6.
$a \times \frac{ {( {x}^{7} )}^{5} \times {x}^{14} }{( {x}^{16})^{3} } = 2012 \\ a \times \frac{ {x}^{35} \times {x}^{14} }{ {x}^{48} } = 2012 \\ a \times \frac{ {x}^{49} }{ {x}^{48} } = 2012 \\a \times x = 2012 \\ x = \frac{2012}{a}$
если а=о, то уравнение не имеет решений.
