Answer:
mass of substance A=1.789
mass of substance B=2.185
now,
mass of substance B - mass of substance A
=2.185-1.789
=0.396
hence
mass of substance B is 0.396 gram greater than the mass of substance A
Answer:
5.) 13,841,287,201 x 2,401. 6.) 64⁴.
Step-by-step explanation:
PEMDAS requires parenthesis first, then exponents, then multiplication/division, and then addition/subtraction. For 5, lets find 7¹². According to my calculations, that is 13,841,287,201. Now for 7⁴. According to my calculations, that is 2,401. Now, we have 13,841,287,201 x 2,401. In math, an expression is a problem. If I solve it, it wouldn't be an expression, so I'll just leave it at that. For 6, we do the parenthesis first. 8² is 64. 64 to the fourth power is 16,777,216. If I solved it, it wouldn't be an expression, so we have to leave it at 64⁴. If you are wondering, 64⁴ is equal to 16,777,216. I hope this helps!
