Find the missing length indicated​
zhannawk [14.2K]

Answer:

x = 135

Step-by-step explanation:

The three triangles are similar.

144/y = y/81

y^2 = 144 * 81

y = 12 * 9

y = 108

81^ + 108^2 = x^2

x^2 = 18225

x = 135

Describe how (2^3)(2^-4) can be simplified
Naddika [18.5K]

Answer:

Add the exponents and keep the bases the same. Then find the reciprocal and change the sign of the exponent

Step-by-step explanation:

When multiplying exponents with the same base number, you can add the powers. (If it was dividing, you would subtract the powers). You would then get 2^{-1}.

  • 2³ = 8,
  • 2² = 4,
  • 2^1 = 2,
  • 2^0 = 1

The pattern is to divide by 2. This means that 2^{-1} would be 1 ÷ 2 which is 1/2.

Tip: Any number to the power of -1 means to give its reciprocal.

Hope this helps!
