What is the simplified form of square root of 144x^36?
trasher [3.6K]

Answer:

The correct option is B.

Step-by-step explanation:

The given expression is

\sqrt{144x^{36}}

Use the property of radicals.

\sqrt{ab}=\sqrt{a}\sqrt{b}

\sqrt{144x^{36}}=\sqrt{144}\times \sqrt{x^{36}}

Use the property of exponent.

a^{mn}=(a^m)^n

\sqrt{144x^{36}}=12\times \sqrt{(x^{18})^2}

\sqrt{144x^{36}}=12\times x^{18}

\sqrt{144x^{36}}=12x^{18}

Therefore option B is correct.

Furkat [3]

Answer:

Step-by-step explanation:

Let the box be y

75% of y = 27

75/100 × y = 27

75y/100 = 27

75y = 27 × 100

75y = 2700

y = 2700/75

y = 36
