<h2>Answer = </h2><h2>=  \frac{1}{y {}^{5} x {}^{2} }</h2>

Step-by-step explanation:

Greetings !

simplify for variable y first

apply exponent rule

a {}^{b} .a {}^{c}  = a {}^{b +c \\   } \\  y {}^{ - 8}y {}^{5}  = y {}^{ - 8 + 3}

Add/subtract the numbers -8+3=5

= y {}^{5}

Apply exponent rule

a {}^{ - b}  =  \frac{1}{a {}^{b} }

Thus,

y {}^{ - 5}  =  \frac{1}{y {}^{5} }

secondly, simplify for the variable x

Apply exponent rule as we made on y

x {}^{ - 2}

x  {}^{ - 2}  =  \frac{1}{x {}^{2} }

multiply bot the values we get

Hope it helps!

Find the length of side AB.<br><br>Give your answer to 3 significant figures.<br><br>HELP NEEDED!
Vladimir [108]

Step-by-step explanation:

solve the equation with formula : SOH, CAH,TOA.

from the above, SOH is to be used to answer the question.

so, Sin∆=Opp/Hyp

∆=41°

Opposite=AB

Hyp= 13.5cm

sin 41°=AB/13.5

sin41°=0.6560

0.6560= AB/13.5

AB=13.5*0.6560

AB=8.856cm

to three significant figure AB=8.86 cm approximately
