Answer 1

Answer:

see explanation

Step-by-step explanation:

A

when 2 equal bases are being multiplied together their exponents are added together, that is

$a^{m}$ × $a^{n}$ = $a^{(m+n)}$

B

$12^{5x}$ × $12^{-7}$ = $12^{5x-7}$

C

$x^{4}$$y^{6k+2}$ × x²$y^{-1}$

= $x^{4}$ × x² × $y^{6k+2}$ × $y^{-1}$

= $x^{(4+2)}$ × $y^{(6k+2-1)}$

= $x^{6}$$y^{6k+1}$

Answer 2

#A

• a^b+a^c=a^b+c

#B

• 12^5x×12^-7
• 12^5x-7

#C

• x⁴y^6k+2×x²y^-1
• x⁶y^6k+2-1
• x⁶y^6k+1
