5 to the 3rd power times 5 to the negative 2 power
Lerok [7]
The equation is 5^{3} × 5^{-2}

First, you need to solve the bases/exponents 

5^{3} is 5×5×5=125

Then you solve the second base/exponent but know that with negative exponents, you divide 1 by the number rather than multiplying


5^{-2}= 1÷5÷5=.04

So now the equation is 125×.04=5

Answer: 5

OleMash [197]

Answer:

diamerer of the hair (t)  3.11 X 10^{-5} m

Step-by-step explanation:

The first dark spot is at the zero location where the glass plates touch. To find the number of dark fringes after first dark fringe, divide 12 cm by 0.75 mm (.075 cm)

12/.075 = 160.0

total number of additional bright fringe is 156 because there is no further portion for extra dark fringe.

diamerer of the hair (t) can be derived as

2nt = (m + .5)*wavelength

2(1.52)(t) = (160.5)(589.3 X 10^{-9})

t = 3.11 X 10^{-5} m
