Write an expression for the sum of a number x and 21 times its reciprocal.
you're kidding, right?
x + 21 * 1/x
or,
x + 21/x
its right / thank you so much!!!
To find the expression for the sum of a number x and 21 times its reciprocal, we can break it down step by step.
Step 1: Express the reciprocal of x
The reciprocal of x can be found by taking 1 and dividing it by x. Therefore, the reciprocal of x is 1/x.
Step 2: Find 21 times the reciprocal of x
To find 21 times the reciprocal of x, we can multiply 1/x by 21. The expression for this is 21 * (1/x), which simplifies to 21/x.
Step 3: Express the sum of x and 21 times its reciprocal
Now, to find the sum of x and 21 times its reciprocal, we just need to add x and 21/x. The expression for the sum is x + (21/x).
In conclusion, the expression for the sum of a number x and 21 times its reciprocal is x + (21/x).
sum ... ? + ?
reciprocal of x ... 1/x
So, what do you think?
