Description

"Multiplication and Division of Quadratic Radicals" Quadratic Radicals PPT Courseware 4

learning target

1. Use the multiplication rule of quadratic radicals: √a√b=√ab to perform relevant calculations;

2. Master the properties of the arithmetic square root of the product: √ab=√a√b and solve problems proficiently.

Multiplying quadratic radicals actually means multiplying the radicands without changing the root sign.

independent inquiry

Use the multiplication rule inversely:√ab=√a√b

written language narrative

The arithmetic square root of the product is equal to the product of the arithmetic square roots of the factors in the product.

Simplification

(1)√200 (2)√x³y（x≥0，y≥0） (3)√(x³+x²y)（x≥0，x+y≥0）

Exploration process: Observe the following formulas and their verification process.

(1)2√2/3=√(2+2/3) (2)3√3/8=√(3+3/8) (3)4√4/15=√(4+4/15 )
