What is a square root?

The Square Root Of A Number Is A Value That, When Multiplied By Itself, Gives The Original Number. For Example, √9 = 3 Because 3² = 9.

What is the rule for multiplying square roots?

To Multiply Square Roots, Multiply The Values Inside The Square Roots And Then Find The Square Root Of The Result. For Example, √2 * √8 = √(2*8) = √16 = 4.

What is a tip for simplifying square roots?

To Simplify Square Roots, Find The Prime Factors Of The Number Inside The Square Root And Look For Pairs Of Factors. For Example, √18 = √(9*2) = 3√2.

Solve for x: √x = 5.

Hint: Square both sides to eliminate the square root.

Square Both Sides: (√X)² = 5², Which Simplifies To X = 25.

Solve the equation: √(x + 3) = 7.

Hint: Start by squaring both sides to remove the square root.

Square Both Sides: (√(X + 3))² = 7², Which Simplifies To X + 3 = 49. Subtract 3 From Both Sides: X = 46.

What is the formula for the square root of a quotient?

The Square Root Of A Quotient Is Equal To The Quotient Of The Square Roots: √(A/B) = √A / √B. For Example, √(16/9) = √16 / √9 = 4/3.

How do you simplify √(50)?

Factor 50 Into Prime Factors: 50 = 25 * 2. Thus, √(50) = √(25 * 2) = √25 * √2 = 5√2.

What is the square root of a negative number?

The Square Root Of A Negative Number Is Not Defined In The Set Of Real Numbers. Instead, It Is Expressed In Terms Of Imaginary Numbers: √(-A) = I√A.

Solve for x: 2√x = 10.

Hint: First, divide both sides by 2.

Divide By 2: √X = 5. Then Square Both Sides: X = 25.
