Square root of 3x^4 times square root of 5x^2 times square root of 10. Multiply and remove all perfect squares from inside the square roots. Assume x is positive.

Step-by-step explanation:

As long as the indices are the same for all the radicals, you can multiply them together. Our index for each of these is 2 (square root) so we multiply them all together and put it under 1 square root sign (radical):

 The largest perfect square in 150 is 25, and the 6th power on the x needs just to be rewritten in terms of an exponent of 2 to give us:

and pull out the perfect squares to get

Step-by-step explanation:

We need to simplify

Right away we can take out the perfect squares. Remember a perfect square is the result of multiplying any value by itself.

d is the answer

step-by-step explanation:

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
