To determine if the equation \( 7 - 4 \cdot \frac{7^3}{\sqrt{49}} = 7 \) is true or false, let's simplify the left side of the equation step by step.
-
Calculate \( \sqrt{49} \): \[ \sqrt{49} = 7 \]
-
Rewrite the equation: \[ 7 - 4 \cdot \frac{7^3}{7} \]
-
Using the Quotient Property of exponents: \[ \frac{7^3}{7} = 7^{3-1} = 7^2 \] Thus, we have: \[ 7 - 4 \cdot 7^2 \]
-
Calculate \( 7^2 \): \[ 7^2 = 49 \]
-
Substitute back into the equation: \[ 7 - 4 \cdot 49 \]
-
Calculate \( 4 \cdot 49 \): \[ 4 \cdot 49 = 196 \]
-
Final calculation: \[ 7 - 196 = -189 \]
Now, we compare the left side, which is \(-189\), to the right side, which is \(7\). Clearly, \(-189 \neq 7\).
Thus, the equation \( 7 - 4 \cdot \frac{7^3}{\sqrt{49}} = 7 \) is false.
The correct response that justifies this conclusion is: False. When applying the Quotient Property, the final exponent is not 1.
