I think there might be a typo in the expression you provided. However, assuming you meant to write:
2x10x10x10x10 + 4x10x10x10x + 8x10x10
We can simplify this expression by performing the multiplications and additions in the correct order. Using the order of operations (PEMDAS), we first perform the multiplications from left to right, and then add the resulting terms.
Multiplying the terms in the first expression, we get:
2 x 10 x 10 x 10 x 10 = 200,000
Multiplying the terms in the second expression, we get:
4 x 10 x 10 x 10 = 40,000
Multiplying the terms in the third expression, we get:
8 x 10 x 10 = 800
Adding the three resulting terms, we get:
200,000 + 40,000 + 800 = 240,800
Therefore, the simplified value of the expression 2x10x10x10x10x+4x10x10x10x+8x10x10 is 240,800.
