WebSquared. Is equal, is going to be equal to r-squared. Is going to be equal to the length of the radius squared. Well, r-squared we already know is going to be 74. 74. And then if we want to simplify it a little bit, you subtract a negative, this becomes a positive. So it simplifies to x plus one squared plus y minus one squared is equal to 74 ...

WebThis property states that when multiplying two powers with the same base, we add the exponents. x^n\cdot x^m=x^ {n+m} xn ⋅ xm = xn+m Example 5^2\cdot 5^5=5^ {2+5}=5^7 52 ⋅ 55 = 52+5 = 57 [Show me why this works.] Practice Problem 1.1 Simplify.

WebSquared means multiplication with the same number. Example - 5 squared = 5 x 5 = 25 10 squared = 10 x 10 = 100 12 squared = 12 x 12 = 144 I hope it’s simple to understand now. Please upvote if you are satisfied … WebRight now, x is only equal to two. Square both sides, and x^2 = 4. For some reason, if you want to take the square root of both sides, and you get x= +/- 2, because -2 squared is still equal to four. But, according to the original equation, x is only equal to 2. Web1. negative of (4 cubed) or - (4)³ = - (4 × 4 × 4) = -64 2. (negative 4) cubed or (-4)³ = (-4 × -4 × -4) = -64 Use parentheses to clearly indicate which calculation you really want to happen. Parentheses don't change your results when the exponent is odd like a 3 but it makes a clear difference when your exponent is even like a 2. improvement in precision proceeding discovery
