Q. Write the expression in simplest form.27x⋅314x2
Write Expression: Write down the given expression.We are given the expression 27x×314x2. We need to multiply these two square roots together.
Apply Property: Apply the multiplication property of square roots.According to the multiplication property of square roots, a×b=a×b. So, we can multiply the square roots together to get 7x×14x2.
Multiply Coefficients and Roots: Multiply the coefficients and the square roots separately.The coefficients are 2 and 3, and the square roots are 7x and 14x2. Multiplying the coefficients gives us 2×3=6. Multiplying the square roots gives us 7x×14x2.
Simplify Inside Square Root: Simplify the expression inside the square root.We have 7x×14x2 which simplifies to 98x3. This is because 7x×14x2=98x3.
Factor Out Perfect Squares: Factor out perfect squares from the square root. We notice that 98 is 49×2 and 49 is a perfect square (72). Also, x3 can be written as x2×x, where x2 is a perfect square. So, we can rewrite 98x3 as 49×2×x2×x.
Take Square Root of Perfect Squares: Take the square root of the perfect squares.The square root of 49 is 7, and the square root of x2 is x. So, we can take these out of the square root to get 7x2×x.
Multiply by Coefficient: Multiply the result by the coefficient from Step 3.We have 6×(7x×2×x), which simplifies to 42x×2×x.
