Can somoene helpme plz...
Simplify
radical 7 * radical 14
wouldn't it be
radical (7*14)
= radical (98)
= 7radical (14)
= 7 radical (2)
The result is right, you erred on the next to last line.
So how do i show that step that i am wrong in...
To simplify the expression √7 * √14, you can follow these steps:
Step 1: Start by multiplying the numbers inside the square roots: 7 * 14 = 98.
Step 2: Rewrite the expression as √98.
Step 3: Simplify the square root of 98. To do this, you need to find the largest perfect square that divides evenly into 98, which is 49.
Step 4: Rewrite 98 as 49 * 2: 98 = 49 * 2.
Step 5: Take the square root of 49: √49 = 7.
Step 6: Combine the square root of 49 with the remaining square root of 2: 7√2.
Therefore, the correct simplification of √7 * √14 is 7√2, not 7√14 as you originally stated.
