Question

Label the equations in number 5-7 as True or False:

Answer 1

Answer:

${ \rm{ {(7}^{1}) ^{9 } = 7 {}^{5} \times {7}^{5} : \: { \tt{ \red{false}}} }} \\{ \boxed{ \mathfrak{correction \dashrightarrow \: ( {7}^{1}) {}^{9} = {7}^{9} }}} \\ \\ { \rm{ \frac{ {y}^{13} }{ {( {y}^{2}) }^{6} } = {y}^{ - 10} \times {y}^{9} : \:{ \tt { \red{false}}}}} \\ { \boxed{ \mathfrak{correction \: \dashrightarrow \: { \rm{{y}^{1} }}}}} \\ \\ { \rm{ {b}^{4} \times {b}^{ - 6} = \frac{ {b}^{1} \times {b}^{3} }{ {b}^{6} } }} \: : \: { \tt{ \green{true}}}$

Answer 2

Answer:

#5 = (7^1)^9= 7^5 x 7^5 - false

The correct thing would be (7^1)^9 = 7^9

#6 = y^13/(y^2)^6=y^-10x y^9 - false

The correct thing would be y^1

#7 = b^4xb^-6=b^1xb^3/b^6 - true
