Q. 4/475582786Which radical expression is equivalent to y83 ?8y3y(3y)8AnthonyBautista
Understand the Problem: First, let's understand the problem. We need to find a radical expression that is equivalent to y raised to the power of 83.
Consider Given Options: Now, let's consider the given options and see which one is equivalent to y83. Option 1: 8y3y Option 2: (3y)8 We need to express these options in exponential form to compare them with y83.
Convert Option 1: Let's convert Option 1 to exponential form.8y3y=y31/y81Using the quotient rule of exponents, we subtract the exponents.y31−81=y248−243=y245This is not equivalent to y83.
Convert Option 2: Now, let's convert Option 2 to exponential form.(3y)8=(y1/3)8Using the power to power rule of exponents, we multiply the exponents.(y1/3)8=y1/3×8=y8/3This is not equivalent to y3/8 either.
Identify Mistake: Since neither of the given options is equivalent to y83, there seems to be a mistake in the options provided. We need to find a radical expression that correctly represents y83.
Express as Radical: To express y83 as a single radical, we can write it as the 8th root of y raised to the third power.y83=8y3This is the correct radical expression equivalent to y83.
