Help please
I have test at monday and i need step by step

Answer 1

5^(1/4) + 4(5)^(1/4) - 2.9.

Explanation:

Let's simplify the expression √√5-2.9+4√√5 step by step:

First, let's simplify the square roots separately:

√√5 = (√5)^(1/4)

Next, let's substitute this value back into the expression:

(√5)^(1/4) - 2.9 + 4(√5)^(1/4)

Now, we can rewrite the expression using fractional exponents:

5^(1/4) - 2.9 + 4(5)^(1/4)

Finally, combining like terms, we have:

5^(1/4) + 4(5)^(1/4) - 2.9

So, the simplified form of the expression √√5-2.9+4√√5 is 5^(1/4) + 4(5)^(1/4) - 2.9.
