Answer:
103000
Step-by-step explanation:
3.5 × [tex]10^{4}[/tex] + 6.8 × [tex]10^{4}[/tex]
Calculate 10 to the power of 4 and get 10000.
3.5 × 10000 + 6.8 × [tex]10^{4}[/tex]
Multiply 3.5 and 10000 to get 35000.
35000 + 6.8 × [tex]10^{4}[/tex]
Calculate 10 to the power of 4 and get 10000.
35000 + 68000
Add 35000 and 68000 to get 103000.
103000
Answer:
Couple of choice:
A. If those x's are the multiplication symbol then your answer is 103,000
B. If those x's are variables then you don't have a definite answer.
Step-by-step explanation:
Explanation for A:
We use PEMDAS and start inside the parentheses
We do exponents before multiplication and get 10,000 for 10^4
10,000*3.5= 35,000
10,000*6.8=68,000
35,000+68,000=103,000
Explanation for B:
If the x's are variables then your question is just and expression. Without it being equal to anything, I can't solve for x. Also if the question was asked as, "What is (3.5x10^4)+(6.8x10^4), when x = 5 (or any random number)" I could solve it because I know the value of x being asked. Maybe try posting the question again if this is what you meant
