Question

64x4y6=8xy5* (4,6,5- степени) (-3ab3)2 *=18 а в11 (3,2,11- степени) -х15у9= (15,9,6,4- степени) *(4х3у)2= 32х12у7 (3,2,12,7- степени) (3в3)2*=72в18 (3,2,18- степени)

Answer 1

$64 {x}^{4} {y}^{6} = 8x {y}^{5} \times 8 {x}^{3} y \\ ( - 3a {b}^{3} ) ^{2} \times 2 {a}^{ - 1} {b}^{5} = 9 {a}^{2} {b}^{6} \times 2 {a}^{ - 1} {b}^{5} = 18a {b}^{11} \\ - {x}^{15} {y}^{9} = {x}^{9} {y}^{5} \times (- {x}^{6} {y}^{4} )$
$32 {x}^{12} {y}^{7} = ...... \times (4 {x}^{3} y) ^{2} = ...... \times 16 {x}^{6} {y}^{2} = 2 {x}^{6} {y}^{5} \times 16 {x}^{6} {y}^{2} \\ 72 {b}^{18} = {(3 {b}^{3} )}^{2} \times ...... = 9 {b}^{6} \times 8 {b}^{12}$
